Paper canisters are the most popular packaging format for Taiwanese specialty tea — but choosing the right structure, lid type, and print finish requires specific knowledge of Taiwan’s supply chain. At RTADV, we have produced paper tea canisters for export brands sourcing Alishan oolong, Oriental Beauty, and Sun Moon Lake black tea. Here is what foreign buyers need to know before ordering.
Paper Canister Structure Options
Taiwan’s packaging factories produce three primary canister structures, each suited to different tea types and price points:
Bottom-Lid Canisters (底蓋罐): The most economical option. A pressed-cardboard bottom is crimped into the tube body. Suitable for mid-range teas in 75g–150g sizes. Unit cost at RTADV: approximately NT$15–NT$22 at 1,000+ quantity. The trade-off is a lower seal integrity, so these must be paired with a heat-sealed aluminum inner bag.
Pull-Ring Canisters (拉環罐): Feature a foil-sealed top with a metal pull ring, similar to a Pringles can. This provides excellent freshness protection without requiring a separate inner bag. Preferred for high-mountain oolong where the unboxing experience matters. Unit cost: NT$25–NT$35. Die-cut fees (刀模費) for custom pull-ring tops run NT$4,000–NT$6,000.
Tinplate-Lid Canisters (馬口鐵蓋罐): A paper tube body with a press-fit metal lid (tinplate or aluminum). The premium option — the metal lid adds weight and a satisfying tactile close. Popular for Oriental Beauty and competition-grade teas priced above NT$2,000 per 150g. Unit cost: NT$30–NT$45. Tinplate lids can be custom-embossed for an additional NT$2–NT$4 per unit.

Moisture Barrier Considerations
Taiwan’s subtropical climate — particularly the plum rain season (梅雨季) from May through June — makes moisture management critical for tea packaging. Ambient humidity in tea-growing regions like Nantou and Chiayi regularly exceeds 80% during this period.
At RTADV, we apply PE (polyethylene) lamination to the inner wall of all tea canisters as a baseline moisture barrier. For higher protection, we recommend aluminum-foil-laminated inner bags (typically a PET/AL/PE three-layer structure) that are heat-sealed after the tea is filled. SGS Taiwan testing confirms this combination maintains moisture content below 5% for 12+ months under standard storage conditions.

Print Effects and Finishing
Canister printing in Taiwan uses offset lithography on pre-printed paper sheets that are then rolled and glued onto the tube body. Common finishing options and their cost impact at RTADV:
Matte/Gloss Lamination: Standard finish, included in base price. Matte is currently more popular among export tea brands targeting Western markets.
Spot UV: Glossy raised coating on specific design elements (logo, tea leaf illustrations). Adds NT$1.5–NT$3 per unit. Requires a separate plate fee of approximately NT$2,000.
Hot Stamping (燙金): Gold or silver foil stamping. The most requested premium finish for Taiwanese tea canisters. Adds NT$2–NT$5 per unit depending on stamped area. Die fee: NT$1,500–NT$3,000.
Embossing/Debossing: Raised or recessed texture on the canister surface. Adds NT$2–NT$4 per unit. Often combined with hot stamping for a layered luxury effect.
Sizing and Pricing Reference
Based on RTADV’s 2025 production data, here are standard canister sizes for Taiwanese tea:
75g oolong: Diameter 85mm × Height 120mm. Price range NT$18–NT$32/unit at 1,000 pcs.
150g oolong: Diameter 85mm × Height 175mm. Price range NT$22–NT$38/unit at 1,000 pcs.
300g (large format): Diameter 100mm × Height 200mm. Price range NT$28–NT$45/unit at 1,000 pcs.
Custom diameters are available but require new tooling (NT$5,000–NT$8,000 one-time fee). In our experience, sticking to standard diameters saves both time and money for first-time orders.
（中文補充：標準尺寸紙罐現有模具可直接生產，客製尺寸需開新模，建議首單先用標準規格降低成本。）
What RTADV Recommends
At RTADV, we recommend that first-time buyers start with a tinplate-lid or pull-ring canister in a standard 85mm diameter. This balances cost, freshness protection, and shelf appeal. For brands planning to sell at premium price points (above US$30 per 150g), invest in hot stamping and spot UV — the per-unit cost increase of NT$3–NT$8 is negligible relative to the retail price but significantly elevates perceived value.
We also recommend ordering a white-sample (unprinted structural prototype) before committing to print production. White samples take 3–5 business days and cost NT$300–NT$500 for a set of 3, shipped internationally via DHL.

Frequently Asked Questions
Q: Can I order paper canisters with my own brand label instead of full custom printing?
Yes. At RTADV, we offer stock kraft or white canisters with custom adhesive labels. This reduces MOQ to 200 units and eliminates plate fees. Label printing starts at NT$2–NT$4 per label for rolls of 500+.
Q: How long does die-cut tooling take for a new canister size?
New die-cut molds (刀模) take 3–5 business days to produce in Taiwan. The fee is NT$5,000–NT$8,000 and the mold is retained at our factory for future reorders at no additional charge.
Q: What is the shelf life of tea stored in a paper canister with aluminum inner bag?
Based on SGS Taiwan accelerated aging tests, properly sealed paper canisters with PET/AL/PE inner bags maintain tea quality for 18–24 months when stored below 25°C and 60% relative humidity. In Taiwan’s summer conditions without climate control, we recommend a 12-month shelf life to account for the plum rain season humidity spikes.

When This Guide Doesn’t Fit Your Project
This guide covers most starter brands and flexible inventory scenarios, but the following are not the right fit — consider alternative suppliers or materials to avoid procurement delays or budget overruns:
- Single SKU annual volume stable above 50,000 units (direct mass production unit cost is lower; small-batch sourcing is not cost-effective)
- Long-term reorders with unchanged specs (no need to resample for evergreen products; the proposal flow is overkill)
- Pure glass / plastic bottles / metal canister sourcing (paper packaging factory MOQ doesn’t fit; find material-specific specialists)
- Pure accessory sourcing (cards, stickers, manuals, corrugated cartons) — use accessory-specific channels
- 45+ day cross-border ocean freight (paper is moisture-sensitive; consider metal / plastic containers or special treatment)
